$I$ is physisorption and $II$ is chemisorption

Vedclass · Answer

(C) Graph $I$ shows that the amount adsorbed decreases with an increase in temperature at constant pressure,which is characteristic of physisorption.Graph $II$ shows that the amount adsorbed increases with an increase in temperature,which is characteristic of chemisorption (as it requires activation energy).Graph $III$ shows the adsorption isotherm at different temperatures,where adsorption decreases as temperature increases $(200 \ K > 250 \ K)$,which is characteristic of physisorption.Therefore,$I$ is physisorption,$II$ is chemisorption,and $III$ is physisorption.Comparing this with the given options,statement $C$ is correct.

The given graphs $I$,$II$,and $III$ represent general trends observed for different physisorption and chemisorption processes under mild conditions of temperature and pressure. Which of the following statements are correct?
